Scientists develop first fabric to automatically cool or insulate depending on conditions

Despite decades of innovation in fabrics with high-tech thermal properties that keep marathon runners cool or alpine hikers warm, there has never been a material that changes its insulating properties in response to the environment. Until now. University of Maryland... Continue Reading →

How Black Holes Nearly Ruined Time

"If black holes truly had no entropy, then any time an object fell into a black hole, its entropy would effectively be deleted, reducing the entropy of the universe and violating the second law of thermodynamics." Black holes are mystifying... Continue Reading →
